Hmm, please keep in mind that in Germany and probably in most european countries it is illegal to record a call. Exceptions are companies which tell you in advance about this issue, usually offer an opt-in (but opt-out is also legal if it is possible to opt-out prior to the recording).
It’s legal to record calls without permission in the UK. If you record someone without their permission and they incur some damages they may sue you for a breach of their privacy, but that is a civil matter. The act of recording calls is not illegal.
(I am not a lawyer and the above does not constitute legal advice)
Ok, thanks. But I would be very careful with such acts and use it only for calls where both parties live and stay in countries where it is explicitely allowed. In Germany such an act is not just illegal, but a major crime.
LinageOS 15.1 now also supports native call recording in the dialer app.
Found it here: This feature is not available for all countries / devices. Remember that you are responsible for complying with any laws, regulations and rules that apply to the use of this functionality and any recordings it produces.
@chrmhoffmann: Is this function in general available for FP2 devices? Is it possible to enable this setting with an ADB command (without self-compiling)?
